Minutes

Attendance on the call was a little sparse - maybe some people have forgotten the change to Mondays.  Next call will be in 2 weeks, Monday March 11.   Clocks will change in US on March 10 and in France on March 31, so be prepared for some changes...

21 cm Cosmology Workshop:   Peter reports that we now have 8 confirmed 'keynote' speakers who will attend.   SOC is continuing to send out invitations.  Next SOC meeting is Monday, March 18.

Report from Jixia about Tianlai array: 

• Dish correlator problem (couldn't reboot) required returning correlator to Beijing.  With help from Institute of Automation the problem was found and repaired - dust on a pin of one of the chips!  H.K. has returned with it to site and will reinstall.
• Broken fiber optic for CNS has been repaired, at least temporarily 

WIYN survey paper:  Haoxuan has made plots of tiles.  Albert - When is next meeting to discuss?  

*Reminder about emailing to the Tianlai list:   Anyone member should be able to email to this list from the email account they used to join it:   [email protected]
